How can you test mobile app performance without a network connection?

Testing mobile app performance without a network connection is crucial for various reasons. It helps ensure functionality in offline scenarios and identifies potential bottlenecks. To do this, you can employ techniques like: Emulators and Simulators: Use tools that simulate network disconnection. This provides a controlled environment to assess app behavior when network access is lost. Mock Data: Implement a system for generating mock data within the app. This allows testing features, even when the device is offline. Airplane Mode: Test the app while the device is in airplane mode to mimic network unavailability. Network Throttling: Gradually reduce network speed to simulate a weak or unstable connection.

There will always be other functional part of an app and logics that do not require internet, and on those functionalities that requires internet connections, connectivity should be monitored and offline mode enabled. In debug mode, you can use mocked data.

Unit tests should be done without internet connection since they should be fast and reliable. Using 3rd party libraries that you cannot control in your tests are not reliable. Mock any 3rd party libraries so you can specific behaviors reliably. Integration tests check communication in between different modules. They should be done in a different test plan since they take more time. But 3rd party libraries should not be tested at all because they are not your responsibility and they are not reliable.

Having an offline mode is important. Users may want to use your app on a plane where wifi is absent or very slow. You must make sure that the experience degrades gracefully. It's also good to test the network request and data your app uses. This way, you may find bugs in your caching policy or the fact that you need to introduce a better caching policy

Testing your mobile app without a network connection is crucial to ensure it works seamlessly in various situations. Imagine users in areas with poor connectivity – your app should still shine! It helps spot and fix issues related to offline functionality, like caching data or syncing changes once online. Testing under diverse network conditions ensures your app remains responsive, efficient, and resilient, providing users a smooth experience, regardless of connectivity challenges.

Testing without a network connection is crucial to ensure your application functions seamlessly in offline scenarios or when network access is unreliable. Here are key steps to conduct effective offline testing: Emulators and Simulators: Use mobile device emulators or simulators that allow you to simulate network disconnection. Mock Data: Implement a system within your app to generate mock data. Airplane Mode Testing: Test your app while the device is in airplane mode or with the network disabled. Network Throttling: Gradually reduce the network speed to simulate weak or unstable connections. Proxy Servers: Set up a proxy server to intercept and block network requests.

For some reason that baffles me testing of intermittent connection is never highlighted enough as a core workflow, seen often as edge/corner case when it absolutely ought not to be. Persisting entered content, auto saving of a form or saved state of progress made are essential to protect your end user likelihood to convert or become a repeat user.

For manually testing slow connections there are a few alternatives: - On iOS Device: Go to Settings -> Developer -> Network Link Conditioner -> Select the relevant profile to test with. - Using proxy tools like Charles Proxy: We can connect the device or simulator/emulator to Charles Proxy and enable throttling via: Proxy -> Throttle Settings -> Enable Throttling -> Specify the network speed you want to test with. The developer can also implement a few automated tests for offline mode/network failures and validate that appropriate data/error message is shown.

ensure that your app is efficient in utilizing network resources, and you can identify and address any bottlenecks or inefficiencies. In addition, local testing using emulators or simulators can help mimic a variety of network conditions, enabling you to assess your app's responsiveness and stability in different environments.

Você já passou pela experiência de usar um app como por exemplo, o Instagram, e ao curtir uma foto, percebeu que estava sem conex?o? E se aquele aplicativo pudesse salvar em memória local a sua curtida, e na primeira oportunidade que o mesmo tiver para se conectar na internet, ele pudesse enviar aos servidores do Instagram aquela sua curtida "offline" e responder par o perfil curtido que houve uma intera??o? Sim, algumas interfaces s?o capazes de lidar com essas intera??es "sem conex?o", por isso é interessante testá-las em ambientes desconectados e verificar se elas s?o mesmo persistidas.
